My daughter and I saw this triangular-shaped silvery object than was like nothing she or I have ever seen.

My daughter and I were in our jacuzzi just looking up at the beautiful blue sky and enjoying the sunshine on this cloudless day. When I looked to the east, I saw this triangular-shaped silvery object. At first I thought it was just a high-flying kite, but it was moving. I then saw a very distinct circular light on the bottom of it. (Also in the sky overhead were several commercial airliners and what looked like a pair of fighter jets; they appeared to be plodding through the sky, compared to the triangle.) The triangle moved in an arc, but faster than anything I have ever seen before. Also, it would hover in one spot for many seconds, then move on. My daughter saw the same thing. She went to get our telescope. When I tried to get a better look, it just disappeared. It also had no contrail. I don't believe in UFO's, but I think I saw my first one. Maybe the military is testing new-fangled things...
